Denver Drain Shop Builds 200-Customer Maintenance-Plan Flywheel

Illustrative case study — Names and exact financials are anonymized. The pattern is composite from multiple operators we’ve installed for.

The setup

A 3-truck drain shop in Denver had a strong call volume — about 280 drain calls per month, mostly residential snake-and-clear at $189–$425 per ticket. The owner had been trying to add an annual jetting / inspection maintenance plan for nine months, attempting to build the workflow inside vanilla GoHighLevel. After three failed iterations (billing wouldn’t auto-retry, reminders weren’t firing, the renewal cycle was broken), the shop had 4 members and zero recurring revenue to show for it.

What changed

The shop installed the Plumbing Snapshot. The maintenance-plan engine shipped with three ready-to-go templates:

• Basic Plan ($19/mo) — annual jetting + drain check + priority booking
• Premium Plan ($29/mo) — Basic + free service call (1/yr) + sewer-line camera every 18 months
• Whole-Home Plan ($39/mo) — Premium + 15% off all work + annual softener service if applicable

Each tech got a tablet-ready enrollment form. End-of-job prompt: “Would you like to never have to call us about a clogged drain again?” Card-on-file collected at enrollment. Auto-billing, auto-reminders 30/14/3 days before annual service, auto-rebook.

The numbers

Week 2: 47 members enrolled, $1,141 MRR Day 90: 89 members, $2,251 MRR Day 365: 211 members, $8,229 MRR

The 94% annual renewal rate was the kicker. Plan customers who experience their annual jetting + drain inspection rarely cancel — the value is concrete and the relationship is sticky. The 6% who do cancel mostly do so because they sold their home.

Why this worked

The maintenance-plan engine ships with three things vanilla GHL doesn’t have: auto-retry on failed cards (3-touch dunning sequence), auto-rebook for annual service (calendar-aware tech assignment), and a renewal flywheel (the annual service IS the renewal event — no separate “do you want to renew?” letter needed).

The tablet enrollment form was the conversion lever. About 1 in 4 service customers said yes when asked at end-of-job. About 1 in 10 said yes when emailed the same offer a day later. The tech-asking-at-the-truck moment was the single biggest enrollment factor.

What didn’t change

The shop kept their existing Service Fusion FSM for job costing. The snapshot handled the marketing layer (review automation, dispatch SMS, maintenance-plan billing) while Service Fusion handled the operational layer (invoicing, payroll, parts costing). Sync via Zapier.
